This article is about the study on construction contractors in Daegu during the Japanese Colonial Rule. The first construction contractors who involved with Kyong-bu railroad work in 1904 personally. But, after they go through the bidding method, changed by the Japanese Government General of Korea in 1922, and the second bid rigging in 1932, contractors was changed gradually the organization into unlimited partnership, limited partnership or stock corporation. The number of them was increased. Most contractors were Japanese, and organized a limited partnership which has been capitalized at 30,000 won. On the other hand, Korean contractors couldn't work at an important part, except for the personal activities of Youngsil Lee(李永實). They were usually employed as consultants or field deputies by Japanese contractors. After the Liberation, Japanese construction contractors returned to Japan, however Tatuoka-kumi(龍岡組), Yasiro-kumi(屋代組) and Sakano-kumi(坂野組) that was leading the business which were took over by Koreans. They were leading architecture field in Daegu.

Most of specifications are composed by letters and the contents of specifications are very bulky. There exists correlation between the detailed contents. Therefore, to be achieved suitable quality of electricity function; it requires effectively organized and well expressed structured system. Therefore, it should be considered that assuring user's safety and guarantee capability of electricity installation through development of making such systematic specifications and supply of a technology that heighten consummative technology. Because the scope of electricity construction that requires making specification is very wide, in order to save resources and improve the level of technology, it is required that the standard of technology that is composed in the electricity construction that is from unit of electricity construction to whole electricity construction should be united and controlled nationally.

Since Jan. 2004, the Ministry of Construction and Transportation has partly introduced estimation system of historical cost data in order to reflect result cost of construction market to cost estimation for public construction. And KEPCO started estimation system of historical cost data in the electrical construction works. Electrical construction cost index a matter of great importance. This paper was conducted to examine estimation methods of the items of the price index estimation system of historical cost data and suggest reasonable applications.

Mutual cooperation between general and specialty contractors for win-win business has recently risen as a buzz word in Korea construction industry. For sustainable mutual cooperation, it is critical to achieve a better understanding of the extent to which general and specialty contractors share critical factors of mutual cooperation. The objective of this study is to identify and discuss key characteristics of perceptions towards mutual cooperation between general and specialty contractors. Key factors for mutual cooperation were identified through a questionnaire survey and statistical tests, and consensus or disagreement as to critical factors of mutual cooperation were identified and discussed.

The purpose of this study is to forecast future changes in the construction market following the reorganization of the construction production system by analyzing the possible market size in which general contractors and specialty contractors may participate in each other, and by carrying out a survey. The ratio of correlation between general construction and specialty construction industries was derived by analyzing the relevance of work area of general contractors and specialty contractors, the similarity of registration standards, and the market in which general contractors and specialty contractors may be able to mutually participate. In order to overcome the limitation of previous studies which analyze the changes in construction market based on the statistical data, and to analyze in more detail the impact of reorganization of construction production system from market participants' view, a survey targeting general contractors and specialty contractors for their willingness and method of participating in the mutual market was conducted. As a result of the survey, it was found that 52% of general contractors were willing to participate in the specialized construction market and 55.1% of specialty contractors were willing to participate in the general construction market. It was found that there was a high willingness to participate in the earthworks, reinforced concrete works, facility maintenance and management, water and sewage facility works, and interior works, and high competition is expected for projects with a scale of 500 million to less than 3 billion won. Through this study, it will be possible for general and specialty contractors to understand the changes in the construction market due to the reorganization of the construction industry production system, and to respond effectively to these changes.

This study deals with construction contract bid-rigging by Japanese contractors who monopolized the construction market of the Korean Peninsula during the Japanese colonial rule, and investigates the abuses of the contract bid-rigging. First of all, construction contract bid-rigging in Korea was triggered by Japanese construction contractors and contract brokers, who had savored the benefits of bidrigging in Japan and had repeated the bid-rigging in Korea since 1903. Second, the agency played a significant role to mediate construction contractors, and existed throughout the Japanese colonial rule on the Korean Peninsula with changing their names. Most of them were engaged in major contract bid-rigging scandals. Among them was Construction Association of Korea, which existed for over 13 years. The agencies had took part in governmental services since the mid-1930s when Japan exploited Korean people during wartime, and focused on sweating human resources for the constructions. Third, one of the biggest construction bid-rigging scandals during the Japanese colonial rule was "the 1st and 2nd scandal on Daegu construction contract bid-rigging." Indeed, the second scandal paved the way for the serial scandals: "Kyeongseong construction contract bid-rigging scandal", "Busan construction contract bid-rigging scandal", and other cases throughout the nation. Fourth, along with the contract bid-rigging cases related to the Japanese Government-General of Korea and local authorities, bid-riggings firmly took rooted in local governments' farmland reclamation projects in the 1920s and the poor relief services in the 1930s. The "bid-rigging charges" forced contractors to compensate their losses with exploiting material costs and labor costs, generating serious problems. The construction contract bid-rigging enabled Japan to monopolize the construction industry and to sweat farmers on the Korean Peninsula. Against this backdrop, contract bid-rigging by Japanese construction contractors during the its colonization made Korean contractors ruled out, and helped Japanese monopolize the industry. A large amount of bid-rigging charges drove Japanese contractors to do fraudulent work with cheap materials and to exploit Korean labor force.

This study suggests architect specialty contractors' strategies by interaction analysis between construction business indicators and business performance indicators. To do this, a database was compiled for construction orders and business performance indicators of specialty contractors with KRW 7 bil. or more of assets of 1997 through 2010. The causal relationship verification and actual proof-oriented analysis were performed for architect specialty contractors. The result is analyzed that their turnover ratio of total liabilities and net worth are affecting obtention of construction orders, ultimately increasing the operating profits. Therefore, this type of specialty contractors is determined to be able to secure corporate stability by establishing a specific operation plan for the total assets.
